To (ZZZlZ hO m airway-concern H v Benit known thatvl, 1 J 01in ULIVtER,a

citizen of the United viitates, and fresident r of Weehawken, in thecounty of Hudson and State of, New Jersey, haveinvented. an ,lmr.provement in Clampiim De-vices, i of wvhich the fcllowinevis aspecification-.5.

The present invention relates to fastening; devices, rand particularlyto those cl-assesl .05 such devices; whichiare intendeduto.vprovidemeans for supporting a @sheet -.-of fELbIlCi'I OI'r-Q members. 5 InSllClli devices 15 it. is, 1 often a the pra cti'ce to apply the; fabricor other material to be supported directly itoathe. support, thefabricrbeing .held; in place-hm applying the, fastening device-toithe 1support, and the tab ric positionede thereo rh This {arrangement has thedisadvantage that the support is often of such-avcharacterthati it isnot de sirablexto .placethe;fabrie orother article directly on thesupport.

It is one of the objects of my invention to provide a fastening devicewhich avoids the disadvantage referred to and which has other desirable.characteristics rendering cits-"applie cation ready and convenient. litis a further object of the present invention to provide a fasteningdevice which is simple in construction and certain and convenient inoperation. These and other objects will be in part apparent and in partpointed out hereinafter.

I have illustrated a preferred embodiment of my invention in theaccompanying drawings, wherein;

Figure 1 is a plan view of a fastening device embodying my invention,the device being shown in open position;

2 is a plan view of the same in closed position;

Fig. 3 is a side elevation of the device in closed position;

Fig. 4 is a cross sectional view of the same in closed position;

Fig. 5 is a plan view showing a plurality of such clamping devices asapplied for supporting a sheet of fabric or similar material.

The fastening device comprises, preferably, a plurality of clampingmembers 1 and 2 which are pivoted to each other intermediate their ends,preferably by providing a pivot pin 3 passing through an aperture 4:

the: wire adj a cent they othen @IldytlSl bywi being In order to moresecurely support a sheet 13 of fabric or the like on the fasteningdevice the: member 11 is provided .1 adjacenti one i endofthc same withthe retainer portion 1 1,

comprising the inclined wedging surface 15., the hollow portion. 16, thehook portion 17, and the auxiliary wedging surface 18. The member 2 isprovided, at that end thereof which corresponds to the end of the member1 provided with the retainer portion 14, with a co op cratingretainerportion 19, comprising the wedging surface 20 cooperating withthe wedging surface 15, the hook portion 21 cooperating with the hollowportion 16, the hollow portion 22 cooperating with the hook portion 17,and the auxiliary wedging surface 23 cooperating with the auxiliarywedging' surface 18.

The device may be used as follows:

Due to. the provision of the slot 5 in the member 1 it will be apparentthat the memhere 1 and 2 are capable of substantially longitudinalrelative movement. The purpose of this movement is to permit the retainer portions 14 and 19 to become separated so that the sheet offabric or other article 13 may be positioned between the same.Furthermore, the provision of the pivot 3 permits the members 1 and 2 tobe rotated with respect to each other. The artive retainer portions 14and 19 of the same,

thefastening device is applied to the support 12 by springing the loop11 over said support. As illustrated, such support may consist of a lineof; rope or wire, and the spring loop 11 is designed and proportioned to'yieldingly attach the associated fastening device to such support. TheWeight of the article'13, or tension exerted on the member 9, or acombination of these two forces, causes the portion 9 of the member 9 toride along the guide-ways or slots 7 and 8, thereby forcing the members1 and 2 into closed position, and, by the relatively longitudinalmovement'of the members 1 and 2 permitted by the slot 5, simultaneouslybringing the retainer portions 14: and 19 into engagement,

as shown in Figs. 2 and 3. In this position.

the article 13 will be securely positioned and supported withoutcontacting with the support 12.

It is of'course to be understood that my invention is not limited to theparticular embodiment illustrated.

Copies of this patent may be obtained for What I claim is:

1. A fastening device comprising a plurality 0f clamping members pivotedto each other intermediate their ends and adapted to be moved into openposition, each of said members being provided with a guideway in oneportion thereof, said members being provided adjacent corresponding endsof the same with cooperating retalner portions and being capable ofsubstantial longitudinal "movement relatively to each other, and

means operating on said members along said guideways to move saidmembers and their associated retainer portions into closed clampingposition by a combined longitudinal and pivotal movement.

2. A fastening device comprising a plurality of clamping members pivotedto each other intermediate their ends and adapted to be moved into openposition, each of said members having a slot therein, said members ibeing provided adjacent corresponding ends of the same with cooperatingretainer portions and being capable of substantial longitudinal movementrelatively to each other, and supporting means for said members passingthrough said slots and adapted to move said members and their associatedretainer portions into closed clamping position by a combinedlongitudinal and pivotal movement.

Intestimony whereof I have signed my name to this specification this 7thday of January, 1918.
